Non-Sexy MPG Advice

This is about as sexy as John Goodman in a speedo but it definitely works, particularly for heavy pickups.

Keep your tires aired up rock-hard.

This is a must for folks with firebomb tires but it makes a big difference on other brands as well.

I use 235-85 E rated tires and I keep them inflated to 80 psi, front and rear. Any more and the tire starts to "crown" - bulge out in the middle of the tread. That will wear the center of the tire out quickly. Not recommended.

My truck is very sensitive to this. If the tires get down to 70 psi, I lose 1 MPG. At 60 psi, 3 MPG. Ask me how I know that. Don't gundeck the tire inflation.

Maybe that's part of why I only get about 14mpg. I ride around at race psi front and rear everywhere. :D
I'm gonna try that on my trip to Panama City this weekend and see what happens. I'll post the results.
